[0029] A limiting plate 8 is provided on one side of the bearing plate 3, and the inner wall of the limiting plate 8 is slidably connected to the outer wall of the bearing plate 3. A plug rod 9 is provided on one side of the limiting plate 8. One end of the plug rod 9 is fixedly connected to one side of the limiting plate 8. A limiting block 10 is provided on one side of the limiting plate 8, and one end of the limiting block 10 is fixedly connected to one side of the limiting plate 8, so that the slider 4 and the limiting rod 7 can be further limited and fixed, and the grinding wheel 2 can be quickly and conveniently limited and fixed;

[0030] A rubber sleeve 11 is provided on one side of the limit plate 8, and one side of the rubber sleeve 11 is fixedly connected to one side of the limit plate 8. A fixing plate 12 is provided on the outer wall of the main shaft 1, and the inner wall of the fixing plate 12 is fixedly connected to the outer wall of the main shaft 1. One side of the rubber sleeve 11 is fixedly connected to one side of the fixing plate 12, thereby further increasing the stability of the limit plate 8 when moving, and protecting the spring 2, thereby improving safety;

[0031] There are two sliders 4 and reinforcement blocks 5, which are symmetrically distributed on one side of the grinding wheel 2. Installation grooves are provided on one side of the slider 4 and reinforcement block 5, and a positioning groove is provided on one side of the bearing plate 3. The outer walls of the slider 4 and reinforcement block 5 are slidably connected to the inner wall of the positioning groove, and a spring is fixedly installed between one side of the extrusion block 6 and the inner wall of the positioning groove. A limiting groove is provided on the inner wall of the bearing plate 3, so that the grinding wheel 2 can be better limited and fixed. When the slider 4 and reinforcement block 5 are inserted into the positioning groove and rotated, the limiting rod 7 can be inserted into the reinforcement block 5 to further increase the limiting fixation.

[0032] The outer wall of the limit rod 7 is slidably connected to the inner wall of the limit groove. There are two insertion rods 9 and limit blocks 10.

[0033] The implementation principle of the grinding wheel spindle quick-release structure of a CNC roller grinder of the present embodiment is as follows: when installation is required, the operator sets the grinding wheel 2 on the outside of the spindle 1, pulls the limit plate 8 to slide on the bearing plate 3, and the limit plate 8 slides to squeeze the spring 2 and the rubber sleeve 11, and the limit plate 8 slides to drive the insertion rod 9 and the limit block 10 to move. At this time, the slider 4 and the reinforcement block 5 installed on one side of the grinding wheel 2 will be inserted into the inner side of the bearing plate 3, and the rotation of the grinding wheel 2 can drive the slider 4 and the reinforcement block 5 to slide. When the reinforcement block 5 is squeezed and contacted with one side of the inner wall of the positioning groove, the grinding wheel 2 continues to rotate, so that the reinforcement block 5 can slide in the slide groove, reducing the distance between the reinforcement block 5 and the slider 4, and the sliding of the slider 4 can squeeze the extrusion block 6 to move, and the movement of the extrusion block 6 can drive the limit rod 7 to slide in the limit groove, and the spring 1 can be squeezed as the extrusion block 6 moves, and the limit rod 7 can be inserted into one side of the reinforcement block 5 as the limit rod 7 moves, so that the grinding wheel 2 can be fixed on one side of the bearing plate 3;

[0034] At this time, loosen the limit plate 8, and the limit plate 8 can be reset by the elastic force of spring 2 and rubber sleeve 11, so that the insertion rod 9 and the limit block 10 can be inserted into the supporting plate 3, and at the same time inserted into the slider 4 and the limit rod 7, and the slider 4 and the limit rod 7 are fixed, so that the grinding wheel 2 can be further fixed on one side of the supporting plate 3, so that it can be used. When disassembly is required, it is only necessary to pull the limit plate 8 to drive the insertion rod 9 and the limit block 10 to disengage from the slider 4 and the limit rod 7, and rotate the grinding wheel 2 to make the limit rod 7 reset by the elastic force of spring 1 and pull out the reinforcement block 5, so that the grinding wheel 2 can be pulled out from the main shaft 1 on one side of the supporting plate 3 to complete the disassembly.
